Recovering IOS on a Catalyst Switch

Lab Prerequisites:

  • This lab will require a REAL switch as this lab cannot be emulated using GNS3.
  • The Cisco IOS on the switch must be corrupt or missing to perform this lab, to emulate this error you can erase the flash memory to practice this lab.
  • An active console session to the device is REQUIRED.
  • You’ll need to use either HyperTerminal or SecureCRT as Putty does not support xModem.

Lab Objectives:

  • Boot the switch into SWITCH ROM mode.
  • Initialize the flash file system.
  • OPTIONAL – Format the flash file system if needed. (This will remove your startup configuration)
  • Set the baud rate to 115200 to increase xmodem transfer speed and decrease time required to restore the IOS Image.
  • Copy the Cisco IOS Image via xModem to Flash:
  • Set the boot parameter to the new image name located in Flash:
  • Unset the baud so that it defaults back to 9600.
